Specification of Letters Patent.

Patented Aug. 20, 1912.

Application filed January 18, 1912. Serial No. 671,813.

To all whom it may concern:

Be it known that I, EDWARD Y. MOORE, a citizen of the United States, residing at Cleveland, in the county of Cuyahoga and State of Ohio, have invented a certain new and useful Improvement in Trolleys, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

This invention relates to trolleys adapted to be propelled on an overhead trackway and the object of the invention is to provide such a trolley with simple and effective means for causing it to take either of a plurality of branches of the trackway, as desired, when it reaches such branch in its travel.

To this end the invention consists broadly of a trolley arranged to travel on an overhead trackway and to support a load, and means mounted on the trolley and adapted to act on the trackway to cause the trolley to select the desired branch.

More particularly, the invention includes movable devices mounted on the trolley frame and provided with an operating handle, whereby they may be thrown, as desired, into position to engage either branch to insure the trolley approaching such track passing onto it in preference to the other branch. Such a combination is valuable in numerous locations, particularly where the track is so high that it can not be conveniently reached from the floor below, and a rope or chain is provided for drawingthe trolley along the trackway. In my invention, such rope or chain not only serves this purpose, but may also operate the handle to control the passage onto the desired branch trackway.

Finally, the particular embodiment of the invention illustrated in the drawings hereof for accomplishing the desired result is also comprised within my invention.

In the drawings, Figure 'l is an end elevation of a trolley equipped with my controlling devices; Fig. 2 is a side elevation of the same; Fig. 3 is a sectional plan of the trackway, illustrating also diagrammatically the trolley and its controlling devices; Fig. 4 is a sectional plan of the trolley, the section being taken through the arms carrying the supporting wheels.

. As shown in Figs. 1 and 4, 10 indicates an Lbeam, the lower flange 11 of which constitutes a trackway. 20 and 20 indicate the the trolley frame.

two halves of the trolley frame, these halves being shown as secured together beneath the flange 11 by the bolts 22. Extending upwardly from each half of the trolley frame is apair of arms, the two arms of the pair being connected by a cross piece 25. The cross pieceand arms are shown as made integral with the frame half 20. Mounted in the upper ends of the arms 23 at the junction of the cross portion 25 are studs 26 on which are journaled wheels 27 which ride on the Ibeam flange 11. The. trolley has suitable means for supporting a load, as, for example, the cross bar 28 mounted in bosses 29 on the frame halves. It is to be understood that the trolley so far described is illustrative of any suitable trolley adapted to travel on the flange 11 and of any suitable means for supporting the load by the trolley. 30 indicatesa pair of frame members secured to the opposite ends of the trolley frame proper, the securement being eflected.

in the form shown by the bolts 81. Each member 30 is formed with a boss 32 at its opposite ends, and in these bosses are down wardly opening sockets-occupied by plungers 34 and by helical compression springs surrounding the plungers. These springs bear at their upper ends against the top wall of the sockets and at their lower ends against annular shoulders provided by enlarged heads on the plungers. Suitable means limit the downward movement of these plungers, the means shown being lips 37 carried by Secured to the frame members 30 at the mid position and projecting longitudinally away from the trolley are studs 40 on each of which is mounted a rocking lever 44, which extends beneath the two plungers at that end, the plungers normally resting upon curved upper edges of the lever. The lever has a hub 41 giving it a bearing on the stud, and it is held in place by the cotter pin 42 extending through the stud. Extending downwardly from the hub of the lever is a lug 43 to which is hinged the handle 45, the hinging being shown as accomplished by a bolt 46. The handle is formed with a loop by which it may be conveniently grasped by the hand or by a suitable hook, and also it preferably has an opening 47 to enable a wire or rope to be more conveniently fastened to it. In

' normal position the handlehangs, as shown in the right hand portion of Fig. 2, with its shank between two lugs 48 formed on the 30. These lugs normally look thehandle and lever against movement, but allow the same to be swung when the handle is moved into diagonal position, as shown in the left hand portion of Fig. 2. Normally, the plungers, lever and handle are idle and both plungers are below the plane of the flange 11. When it is desired, however, to guide the trolley ontothe branch trackway, the handle (swung longitudinally to release it fromthe lugs 48) furnishes means by which the lever 40 may be locked toraise either plunger, as desired. Now,-with the plunger raised, if the trolley is propelled along the. trackwayto a junction of branches, the raised plunger will engage the I outer side of' the corresponding branch trackway and cause the trolley to twist about a wertical axis as it proceeds, so that it runs ontotha't branch in preference to theother .Fig. 3 illustrates a main'trackway and two --branches,-the main trackway being designated l1 and thebranches 11 and 11 1 All offthese trackways are of I-beam con-- struction and the lower'flange 11 is shown I" as brought to a point extending between the flanges 11 and 11,which' are cut oil diago- 30.

nally, leavinga space between them and the point for the passage of the arms 23. The

In such movement, the han 1e naturally as-' sumes the diagonal position shown in the left hand portion of Fig. 2, so that a simple rocking of it on the stud 40 in the desired neath the plungers; 1

direction insures the trolley taking the proper branch. When the trackway is so high that the handle is out of reach of'an operator on the floor, the same result fol lows when a rope or chain is fastened to the handle. .7 The operator, in dragging the trolley after himby such rope, holds the handle in the diagonal position and simply plunger to cause the hoist to take the de transverse rocking lever pivoted inter-med? my invention, what ately on the frame'andextending" trans r versely of the plungersyand adapted to elevate either into positionto engage the'outer edge of a corresponding branch trackway.
